Metodo para la deteccion de la yema de huevoMethod for egg yolk detection
La presente invencion se refiere a un metodo para detectar la yema de huevo en la clara, por ejemplo, pero no exclusivamente, al menos una mancha de yema, que comprende:The present invention relates to a method for detecting egg yolk in the white, for example, but not exclusively, at least one spot of yolk, comprising:
- romper un huevo,- break an egg,
- separar la clara y la yema,- separate the white and yolk,
- recolectar la clara y la yema por separado en una taza para yema y en una taza para la clara,- collect the white and yolk separately in a cup for yolk and in a cup for white,
- formar una imagen de la taza para la clara sustancialmente desde arriba con una camara, de manera que se obtiene una imagen de la clara; y- forming an image of the clear cup substantially from above with a camera, so that an image of the clear is obtained; Y
- proporcionar una caractenstica de la imagen de la clara.- provide a characteristic image of the white.
El documento US2008 /292758 describe un metodo y un aparato para monitorear la ruptura de los huevos. El monitoreo consiste en que se registre automaticamente la presencia de al menos una de las condiciones (a) el huevo se deja caer, (b) la cascara de huevo no se ha roto (c) se rompe la membrana de la yema, y que la presencia de una anomalfa en la ruptura del huevo se presente a un operador. La presencia de un huevo no roto puede detectarse como la ausencia de contenido en el dispositivo receptor de huevo, mientras que la presencia de un huevo con una membrana de la yema rota puede detectarse por la presencia de yema en la clara.US2008 / 292758 describes a method and an apparatus for monitoring the breaking of eggs. Monitoring is that the presence of at least one of the conditions is recorded automatically (a) the egg is dropped, (b) the eggshell has not broken (c) the yolk membrane is broken, and that The presence of an anomaly in the egg rupture is presented to an operator. The presence of an unbroken egg can be detected as the absence of content in the egg receptor device, while the presence of an egg with a broken yolk membrane can be detected by the presence of yolk in the egg white.
Romper huevos y recolectar la yema y la clara por separado a escala industrial, con los llamados separadores de huevo, se conoce generalmente. Mas particularmente, se conoce llevar a cabo una inspeccion despues de la recoleccion, para comprobar si algo de la yema ha terminado en la clara, y tambien para limpiar las partes respectivas despues de cada operacion de ruptura. Usualmente, las piezas para romper los huevos por un lado, y para recolectar la yema y la clara por otro lado, se elaboran de acero inoxidable. Con el fin de que estas piezas - es decir, las pinzas para sujetar el huevo antes de la ruptura y sujetar las mitades de la cascara del huevo despues de la ruptura, la cuchilla para la ruptura, la taza para yemas para recolectar la yema, mas a menudo intacta, despues de la ruptura, y la taza para clara para recolectar tanta clara como sea posible- puedan limpiarse lo mejor posible, este acero se pule electroltticamente. En la limpieza dclica habitual, estas superficies pulidas se revelan inmediatamente si queda algun residuo.Breaking eggs and collecting the yolk and white separately on an industrial scale, with the so-called egg separators, is generally known. More particularly, it is known to carry out an inspection after the collection, to check if some of the yolk has finished in the egg white, and also to clean the respective parts after each breaking operation. Usually, the pieces to break the eggs on the one hand, and to collect the yolk and the white on the other hand, are made of stainless steel. In order that these pieces - that is, the tweezers to hold the egg before the break and hold the halves of the eggshell after the break, the blade for the break, the cup for yolks to collect the yolk, more often intact, after the break, and the clear cup to collect as clear as possible - can be cleaned as best as possible, this steel is electrically polished. In the usual cycle cleaning, these polished surfaces are revealed immediately if any residue remains.
Por ejemplo, en el documento US5293815, se destaca que las tazas de acero inoxidable con una composicion seleccionada adecuadamente tienen la ventaja de una buena limpieza. En "EFFECTIVE CLEANING OF STAINLESS STEEL SURFACES", TNO, en el sitio web
www.tno.nl, se mencionan piezas de maquinas para el procesamiento de alimentos y componentes alimenticios que se fabrican de acero inoxidable pulido electrolfticamente, y se destaca que son muy faciles de limpiar adecuadamente.For example, in US5293815, it is emphasized that stainless steel cups with a properly selected composition have the advantage of good cleaning. In "EFFECTIVE CLEANING OF STAINLESS STEEL SURFACES", TNO, on the website
www.tno.nl, parts of machines for food processing and food components that are made of electrolytically polished stainless steel are mentioned, and it is noted that they are very easy to clean properly.
Aunque el acero pulido es muy adecuado para tales maquinas, este puede reflejarse de una manera desventajosa, en particular cuando se aplica la tecnologfa de vision. Esta tecnologfa de vision se describe, por ejemplo, en el documentoWO2007129349, donde se observan los residuos de la yema en la clara en bandejas de recoleccion. Ademas, cuando se usa tal tecnologfa de vision en los separadores de huevo con transportadores sin fin con tazas para la clara y la yema, los sistemas de camaras se usan para tomar imagenes de cada combinacion consecutiva de taza para clara/yema o unidad de taza separadora. Con esto, pueden rastrearse lo posibles residuos de yema en la clara. La exposicion y formacion de imagenes son tales que con una taza de dicho acero pulido se producira la reflexion. Como se conoce en este campo de tecnologfa de procesamiento de alimentos, esto a menudo conduce a la caracterizacion incorrecta de dichas tazas. Mas particularmente, esto significa que la taza para claras puede proporcionar una imagen como si estuvieran presentes residuos de la yema. Tras la evaluacion, tales tazas se rechazan y por lo tanto se conocen como "falsos rechazos".Although polished steel is very suitable for such machines, it can be reflected in a disadvantageous manner, particularly when vision technology is applied. This vision technology is described, for example, in document WO2007129349, where the yolk residues are observed in the egg white in collection trays. In addition, when such vision technology is used in egg separators with endless conveyors with cups for egg white and yolk, camera systems are used to take pictures of each consecutive combination of cup for egg white / yolk or cup unit separator With this, the possible yolk residues can be traced in the egg white. The exposure and formation of images are such that with a cup of said polished steel reflection will occur. As is known in this field of food processing technology, this often leads to incorrect characterization of such cups. More particularly, this means that the clear cup can provide an image as if yolk residues were present. Upon evaluation, such cups are rejected and therefore known as "false rejections".
Con el fin de remediar este inconveniente de reflexion, el metodo de acuerdo con la presente invencion se caracteriza por las caractensticas de la reivindicacion 1.In order to remedy this inconvenience of reflection, the method according to the present invention is characterized by the features of claim 1.
De manera ventajosa, las tazas existentes y la forma de fabricacion de estas pueden mantenerse, mientras el reconocimiento de la yema en la clara se mejora considerablemente. En particular, una mejora significa que ocurran menos llamados "falsos rechazos". De manera ventajosa, pueden realizarse ademas determinaciones correctas del color amarillo en la taza para clara. Mas particularmente, las caractensticas de acuerdo con la invencion permiten un mejor reconocimiento de las reflexiones del acero que tiene propiedades de color que se desvfan de la deteccion del color deseado, de manera que las tazas aprobadas manualmente normalmente no se rechazan despues, incluso, a traves de tal tecnologfa de vision. En la taza para clara, tambien se realizan ahora adecuadamente las determinaciones correctas del amarillo.Advantageously, the existing cups and the manufacturing method of these can be maintained, while the recognition of the yolk in the egg white is considerably improved. In particular, an improvement means that fewer so-called "false rejections" occur. Advantageously, correct determinations of the yellow color can also be made in the clear cup. More particularly, the features according to the invention allow a better recognition of the reflections of the steel having color properties that deviate from the detection of the desired color, so that the manually approved cups are normally not rejected after even through such vision technology. In the clear cup, the correct yellow determinations are now also properly performed.
En una modalidad adicional de esta invencion, el metodo tiene una o mas de las caractensticas siguientes: que para la subarea preseleccionada de la taza para clara se mantiene que Pa/Aa > 0.80;In a further embodiment of this invention, the method has one or more of the following characteristics: that for the preselected subarea of the cup for clearing it is maintained that Pa / Aa> 0.80;
que ademas, para una mancha de yema Aya, se determina un tamano que ademas incluso, en la caractenstica esta comprendida Aya/Pa,that in addition, for a spot of bud Aya, a size is determined that in addition even, in the characteristic it is included Aya / Pa,
que las superficies de las areas se miden en pfxeles o derivados de estos.that the surfaces of the areas are measured in pixels or derivatives thereof.

-para Sy, el area de color de la yema, como una denotacion del espacio de color, en el que se mide el amarillo de la taza para yema, y- for Sy, the color area of the yolk, as a denotation of the color space, in which the yellow of the yolk cup is measured, and
-para Fy, el area de medicion de la yema, como una denotacion de esa parte de este espacio de color, tambien referido como "figura", que forma el lfmite para los tonos amarillos espedficos que se observan en el caso de una taza para yema espedfica. Fy tambien puede denominarse un filtro para yema o filtro.-for Fy, the area of measurement of the yolk, as a denotation of that part of this color space, also referred to as "figure", which forms the limit for the specific yellow tones observed in the case of a cup for Specific yolk Fy can also be called a filter for yolk or filter.
En esta Figura 2, la subarea Py se representa de forma sombreada para indicar asf que la yema esta presente. Su color se mide en el espacio de color Sy mencionado. Despues, se selecciona una parte espedfica en el espacio de color Sy, es decir, el area de medicion de la yema Fy anteriormente mencionada, que puede considerarse asf como un filtro para yema o filtro. Con este filtro Fy, se observa la subarea Pa en la taza para clara (llena con la clara 300 durante su uso). Como puede observarse en esta Figura 2, un sombreado como en la subarea Py no esta en evidencia, lo que significa, por lo tanto, que en la clara, mas particularmente en la subarea Pa, no se ha encontrado yema.In this Figure 2, the subarea Py is represented in a shaded way to indicate that the yolk is present. Its color is measured in the color space Sy mentioned. Then, a specific part is selected in the color space Sy, that is, the measurement area of the aforementioned yolk Fy, which can be considered as a filter for yolk or filter. With this Fy filter, the subarea Pa is observed in the clear cup (filled with clear 300 during use). As can be seen in this Figure 2, a shading as in the subarea Py is not in evidence, which means, therefore, that in the clear, more particularly in the subarea Pa, no yolk has been found.
Es claro ademas que en el contorno de la taza para clara 30a, la subarea Py forma una parte de toda el area Aa. Como la yema terminara en la clara virtualmente de forma exclusiva por encima de la segunda parte inferior 33, y una camara representara especialmente esta parte de la taza, la subarea Pa se define especialmente por encima de esta parte inferior. Para maximizar la posibilidad de descubrimiento, de acuerdo con una modalidad preferida, se selecciona Pa/Aa > 0.80. Aqrn, por ejemplo Pa/Aa es una relacion de superficie de las areas respectivas. Como se menciono, las superficies de las areas pueden medirse por ejemplo en pfxeles o derivados de estos.It is also clear that in the contour of the cup for clear 30a, the subarea Py forms a part of the entire area Aa. As the yolk will end in the clearing virtually exclusively above the second lower part 33, and a chamber will especially represent this part of the cup, the subarea Pa is especially defined above this lower part. To maximize the possibility of discovery, according to a preferred mode, Pa / Aa> 0.80 is selected. Here, for example Pa / Aa is a surface relationship of the respective areas. As mentioned, the surfaces of the areas can be measured for example in pixels or derivatives thereof.
En la Figura 3, se muestra una vista similar. A diferencia de en la Figura 2, aqrn, en la subarea Pa se representa un residuo de yema Aya, el residuo de yema forma un conjunto de pfxeles con un color que se hace visible por medio de la accion del filtro en Fy anteriormente mencionado, y que, en otras palabras, tiene un color localizado en el area de medicion de la yema Fy. Basado en esta comparacion, se hace una eleccion como se indico aqrn anteriormente, es decir, "ADECUADO" o "NO ADECUADO" para un procesamiento posterior, lo que significa -hacer un uso adicional de cada una de los lfquidos de las tazas, o -hacer un uso adicional de uno de los dos, o -no hacer un uso adicional de ninguno de los dos.In Figure 3, a similar view is shown. Unlike in Figure 2, here, in the subarea Pa a yolk residue Aya is represented, the yolk residue forms a set of pixels with a color that becomes visible by means of the aforementioned filter action in Fy, and that, in other words, has a color located in the area of measurement of the yolk Fy. Based on this comparison, a choice is made as indicated hereinabove, that is, "ADEQUATE" or "NOT SUITABLE" for further processing, which means - make additional use of each of the liquids in the cups, or - make additional use of one of the two, or - do not make additional use of either.
De esta manera, se establecen las propiedades de la yema anteriormente mencionadas. Mas particularmente, se determinan las propiedades de color en uno de los espacios de color Sy anteriormente mencionados.In this way, the aforementioned yolk properties are established. More particularly, the color properties in one of the color spaces Sy mentioned above are determined.
En una modalidad adicional, el tamano de la mancha de yema Aya, como una medida de la cantidad, tambien puede desempenar un papel en esta decision. La caractenstica mencionada puede comprender, por ejemplo, Aya/Pa (en particular la relacion de superficie entre la superficie de la mancha Aya y la superficie de la subarea Pa).In a further embodiment, the size of the Aya bud spot, as a measure of the quantity, can also play a role in this decision. The aforementioned feature may comprise, for example, Aya / Pa (in particular the surface relationship between the surface of the spot Aya and the surface of the subarea Pa).
